'Bc'itknownt at we, Loms G. Mnnan and .EnwmurC. Lone, both citizens of the United States, and residents of the borough of Westmont, county of Cambria, "and State of Pennsylvania, have invented certain new and useful Improvements in Gar-Door Constructions; and we do hereby'declare the following to be a full, clear, and exact description of the invention, such as will onable others skilled in the art to which it appertains to make and use the same.

Our invention relates ,to improvements in car door construction with particular reference to the support and pivot of drop doors of ondola, hopper and othercars.

ne of the objects of our invention is to provide a .sim le and cheap construction whereby the e go of the door which is adjacent the hopper sheet, is firmly supported and at the same time adapted to revolve about or upon said support for the urpose of opening and closing the door w ile the sup orting .porti'on itself'which is attached to t e hopper sheeft aids in strengthening and stiflenin the sgme, thus obviating separate suppo ing and stifl'enin members.

,Having thus given a. enera description of our invention, we wi l now,-in order to make the matter more clear refer to the annexed sheet 0 drawings formin part of this specificati n and in which li e characters refer to like parts. Figure 1 is a vertical sectional elevation through the lower portion. of a hopper car .showing the application of our invention. Fig. 2 is ajvertical larged scale of-one \gorm of our car door stiction on a slightly eneonstruction. Figs. 4 and 5 are views similar to Fig. 2, but showing modified;

of our construction using difi'erent shapes of stifl'ening and supporting members as illustrated. Fig. 6 illustrates in side elevations, pressed metal door support of general Z-shape. Fig. 7 is an end elevation forms,

of, the door su port illustrated in Fig. 6.

- Figs. 8 and 9 il ustrate in Sections] elevation the hinge or pivot end of one form of our car door. Fig. 10 is a plan and 11 a sectional elevation of another form of the hingeor pivot and of. our car door. Fig. 12 1s a s de elevation of one form of our car door reta1ning bar and Fig. 13 illustrates another form of same.

Referring now to the characters of reference on the drawings 2 1 represents the portion of the car in general adjacent to the dump doors. thereof, 2 are the hopper sheets B s ourcar door sup rt shown as a rolled Patented Oct. as, 191d. 1

Z-har which is secure y.riveted to the hop;,a0

per plates b one of its flange with its web project ng ownwardly and its other flange pro ecting toward'the door opening in such a wayas to serve as'a support for the end of the car door,.as illustrated. The car in general 18 4, the spreader bars secured to the car doors are 5, theseepreade bars being adapted to be secured. to the two adjacent doors and to which the door liftimand lowering mechanism (not show?) I: attached. The car door is preferably 0 pressed metal and is provided with a curled hinge-end 6, as illustrated, this end being formed of a proximately semicircular section, the insi e of which is adapted to fit over the hinge bar or pm 9 and the outer surface of.wh1ch is adapted to rest upon, turn u on, and be supported by, the flange of the oor support. T e

hinged end of the car door is rovided with notches 7 adapted to receive t e downturned ends of the hinge 'bar 10, as illustrated particularly in Fig. 12, this end being provided with nuts 11 to secure the hinge bar in place and the ends 10 may "be riveted over the nuts to add to the securit thereof. The portions adjacent the notches are reinforced by integral pro'ections 8.

As illustrated in I ig. 3, 12 is another slightly modified form of binge bar which is riveted in place by the rivet heads 13 but is otherwise similar to that illustrated in Figs? and 12; while 14' is the hopper sheet extension adapted to reject over the bent end of the door, as ilustratcd, to form a closure therefor and to prevent the lading from fouling the hinge, and this is equally true of the other constructions shown in which, however, the hopper sheet projectime are slightly shorter.

As illustrated in Fig. 4, 15 is a hopper sheet stiffener or door support of channel section instead of the Z-bar illustrated in Figs. 1, 2 and 3, and 17 are perforated eyeends of another slightly modified form of rctaini'ngbarlfi further illustrated in Fig. 13, u'l1ich bar is adapted to be secured in place to the lower flange of the channel 15 y means of rivets 18'.

As illustrated in F i s. 6 and 7, 19 is a do support and hopper p ate stiffener formed of pressed metal ap roximately of Z-section and provided wit depressions or corrugations 20therein for the purpose of stifl'ening the same, and 21 are offset portions of the curved hinged end of the door adapted to stiffen the same and form bearings therefor, as illustrated in Figs. 8 and 9.

As illustrated in Fig. 5, 22 is another slightl modified form of door support of presse steel provided with a lower supporting portion or flange 23 and an upper portion 24 secured to the door hopper plate 2.

Our door support and hop or plate stiffener is adapted to be secure to the lower portion of the hopper sheet and thereby to strengthen and sti en the same, thus obviating the necessity of special hopper sheet summers and the integral hinge construction of our door end in combination with the supporting and stifiening member obviatcs the use of the usual forged strap hinges which are generally heavy and expensive. Our construction, therefore, conduces to lightness and economy of construction, maintenance and repair.

Our construction is such that the outer curved end of the door rests upon and is adapted to be rotated upon thelower flange of the door sup ort and stiffening member, while the function of the hinge bar is principally to retain the door in position and to guide the curved and during the rotation of the door. In,

Althoughwe have described and illustrated our invention in considerable detail, we do not wish to be limited to the exact and specific details thereof, as shown and described, but may use such modifications in, substitutions for, or equivalentsthcreof, as are embraced within the scope of our invention, or as pointed out in the claims.

Having thus described my invention, what we claim and desire to secure by Letters Patent is: i

1. In a car, a door 5 porting member secured to and adjacent the edsze of the hp per sheet and provlded with a flange adiipted to directly receive and support the end of the door, and mean. for retaining said in rotative positio thereon. a

2. l car, a door supporting member secured to the hopper sheet ad acent the lower edge thereof comprising a flan ed member, one flange of wiich is secure to the hopper sheet and the other flange spaced apart therefrom and adapted to directly support a door provided with a curved end bar of U-shape the intermediate -which is fitted within said curve and means for retaining said end in position thereon.

3. In a car, the combination with the hopper sheet, of a flan (1 member secured thereto and provided with a door supporting ortion below said sheet adapted to direct y receive and support a door provided with a curved end, and a retaining bar located within said curved end and secured to said supporting flanged portion.

4. In a car, a flanged door supporting member secured to the hopper sheet rovided with a flange spaced apart there rom and adapted to support the door, the end portion of which is offset and bent approxi-.

mately in the form of a semi-circle with its convex side resting upon and supported by said flange, and means for retaining'said curved portion in rotatable position thereon.

5. In a car, a supporting member secured to the hopper sheet provided with a flange spaced apart therefrom and adapted to directly support the end of a door, provided with an offset and curved end approximately in the form of a semicircle, a round ortion of end and thedend portions secured to the flange afore- Sal 6. In a car, a door supportingmember secured adjacent the lower edge of the hopper sheet, comprising a bar having a web portion with upper and lower flanges extending at angles thereto, "one of said flanges being attached to the hopper sheet; a retaining bar st cured to the other flange; a car door having a curved end, the convex ortion of which is supported upon the utter flange and maintained in place by a retaining pin, the bod y of which is located within the cavityof said curved end.

7. In a car, a door supporting member secured to and adjacent to the edge of the hopper sheet, comprising a bar having a web portion with flanges extending from each edge of the web portion, one of theflanges being secured to the hop er sheet; a door having its upper edge 0 partially hollow cylindrical curvature the convex side of which is supported on the upper portion of th other flange, and means coiiperating with he concavity of said door edge for retai ng the same in rotatable position there In witness whereof we hereunto afiix our signatures.
